2022 Lexus RX450h

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2022 RX450h.

Transmission Automatic (AV-S6)

The 2022 Lexus RX450h comes with an automatic AV‑S6 transmission, runs on 0W‑20 oil that is circulated through an oil cooler, and is rated by the EPA at 31/28/30 mpg. Owner feedback for this model year shows only three total complaints, with service brakes noted as the most frequent issue, and the vehicle has been subject to four recalls. Compared with the broader 2011‑2023 complaint trend — where the peak year (2017) logged 55 complaints and the low point (2023) just one — the 2022 RX450h’s modest tally places it near the better‑end of the reliability spectrum, suggesting a generally dependable iteration.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 60,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2022 Lexus RX450h (target year) reports only one complaint each in “Service Brakes” and “Steering, Service Brakes,” with zero crash or fire complaints. This minimal complaint volume matches the 2023 model year, which also recorded a single complaint and no recalls or investigations, and it is far lower than the peak 55 complaints seen in 2017. Across the generation, complaint counts rose through 2017 then fell steadily, while recalls were limited to two occurrences in 2016 and never exceeded that number. Consequently, the 2022 model falls at the low‑end of the complaint arc, sharing the same sparse reporting as the subsequent year. For these reasons, the 2022 RX450h can be considered a good year to buy from a regulatory‑record standpoint.
